Is massive geo-engineering a viable solution?Adding lime to sea water helps dramatically reduce CO2 levels in the atmosphere, according to new scientific research which is being funded by Shell. Lime increases alkalinity in the water, which boosts its ability to absorb CO2. It also reduces the water’s tendency to release the CO2 back into the atmosphere again.
